Before I start my rant of the day, I need to do something slightly responsible:

If you have come here because you have lost your Yamaha XMAX key fob and are currently stranded or just trying to figure out how to get your bike running again, go read this thread as it is the primary resource I used in the same situation and I feel you shouldn’t need to read the next several paragraphs of text before I link it.  Also, look up “Emergency mode” in your manual or scroll all the way to the bottom of this post where I have put a screenshot of the pages talking about it.

OK, moving on now:

I alluded to losing a family member recently.  This is the first time either my wife or I has lost a parent, and thinking about how we are almost certainly going to go through the experience three more times has been a challenge.  That’s not really a topic for today, though, because that is just a little TOO depressing.

Instead, I’d like to talk about how educational the whole situation has been, because I have had to learn about so many things that I’ve never really thought about.  It turns out that there are a lot of people who you will never talk to in your daily life but their job is to deal with the least pleasant aspects of what comes after your daily life.  Like, polite people come to your house with a stretcher and someone disappears and then you have a muted conversation in a somber office and at the end of it all you have official forms that you can give to banks to prove that someone is no longer around and you have a heavy cardboard box of ashes.

AND ALSO YOU NEED TO DEAL WITH ALL THE CRUD THEY HAVE BEEN HOARDING FOR DECADES BUT THAT IS NOT A TOPIC FOR TODAY.

It was when the funeral home called me to tell me that the box was ready for pickup that I had an idea that unfortunately led to another impromptu educational opportunity.

See, I’ve only owned a motorcycle scooter for about 8 years now, and neither of my parents had ever been in good enough health to be a passenger.  My thought was, I will go pick them up and they can come home in the top case and they will officially have had a ride on the bike.  These are the sort of weird things you think about.

So, I went out to the bike,  cleaned out the top case to make room, and rode over to the funeral parlor – about ten miles away.  When I turned OFF the bike, however, it made a beeping sound I had never heard before and the “lock” indicator on the dashboard flashed angrily in a way that was likewise entirely novel.

I tried to start the bike again, and it was completely unresponsive, and then I realized that I had last seen my keys when they were sitting in the lock of the top case, ten miles ago, and that said keyhole was now conspicuously vacant.

A visual guide. Do not be like me. Do not do this.

Putting two and two together didn’t take a calculator.  The sequence of events had obviously been something like this:

1. While the keys dangling behind me in the lock of the top case weren’t SUPER close to the dashboard of the bike, they were close enough for the computer to recognize that the key fob was in the range where it would start the bike.
2. At some point during the ride, the bumping and vibration of the road had made them slip out, but since the engine had already been started there was no need for the bike to check whether the fob was nearby.
3. When I turned the ignition off, the bike did a check and screamed at me to let me know that I had been a blithering idiot.

The sum of this particular equation was that I was standing in a parking lot, ten miles from home, with a bike that couldn’t be started and couldn’t be secured because opening the seat to get my disc lock or chain needs the key fob and even engaging the steering lock, for all the good that does, needs the fob as well.

It was also nearly 4 PM at this point.

I understand that panicking is the last thing one wants to do in this scenario, but starting the recovery process with a few minutes of it helped to clear my head a little bit.

So. Panicking done.  Priorities.  I went into the funeral home and signed for the ashes.  Those came back to the parking lot with me.  It was now after 4.

The bike had come with two fobs.  The second was in my safe deposit box, in a bank that closed at 5 PM, that I might have been able to get to in that time… but only if I left a completely unsecured bike sitting completely in the open.  Oh, and I didn’t have my safe deposit key on me and the cost of drilling a safe deposit box open is, ahem, prohibitive.

The only thing that saved me was that, while I don’t have many friends in the world and even fewer that are anywhere nearby, the one who still DOES live nearby is the sort of person who asked absolutely zero questions when I texted them, in a panic, asking them to go collect my wife, get her to the bank so she could get something out of a safe deposit box, and get both to me at my current location, and do all of this in the next hour if they wouldn’t mind.

Also there was a frantic phone call home to tell my wife that someone would be arriving soon and whisking her off to a bank.

Normally I’d say “this is the kind of friend who would help you hide a body” and while this is probably the case it feels a little too close to home in this specific scenario.  Suffice to say, I owe them pretty much any favor they ask of me at any time in the future.

They even shared their location with me, so I could watch a little dot move across a map, with rush hour traffic serving to make my panic levels nice and spicy.

Thankfully, even with traffic it wasn’t TOO long before a black SUV pulled up, my wife in the passenger seat, and I traded her a heavy cardboard box for a new key fob, confirmed that it started the bike, and watched them disappear into the sunset – they WERE heading west, and it WAS setting, this isn’t just me being poetic – before I started retracing my steps, hoping against hope to see my keys winking at me from a gutter.

Spoiler: Nope!  I went back and forth along my route, the entire ten miles, several times that day and over the next week, with no joy.

So, while I could now start and ride the bike again, I was in the position of only owning a single fob.  Oh, and also I lost a bunch of other keys, but none of them were as important so they weren’t really occupying head space.

Replacing a fob at the dealership is… expensive.  A few hundred bucks.  I really didn’t want to spend that, and I didn’t want to explain the whole story to a bunch of strangers at the dealership.

(He says this, while explaining the whole story to a bunch of strangers on the internet.)

So I went looking for solutions, and found the thread I linked earlier, where a bunch of strangers on the internet talked about how to fix the situation I was in.

And this is where the Middle Kingdom came to my rescue, because it turns out that you can buy replacement fobs off AliExpress for like 30 bucks.  You need to be careful about getting the one that operates on the same frequency your bike uses, but thankfully there was an FCC ID printed on the fob I still had and that took me directly to a page on the FCC site that spelled it out for me.

The specific one I got was this one, but if you are in my situation you may want to do your own research.

Every fob comes with a little red piece of paper with a six-digit code printed on it.  I don’t know if there’s an official term for this, but I’m going to call it the prefix code.  Once the key is registered with the bike, this code can be used to emergency start the bike – so technically I was NOT really stranded in that parking lot, that’s one more lesson – and also can be used to register new keys.

The process of registering it is a bit tricky, and this is probably by design.  You need to press and hold the ignition button in a specific pattern to get the bike into a mode where it accepts the prefix code, and then you need to enter the prefix code by holding the ignition button while a light flashes and releasing at the right time, and then there’s an extremely narrow window at the end of all this where you can press a button on the new fob – a short press, not a long press –  and the bike will accept it.  Even with watching two videos on the topic – bless you, bike YouTubers – it still took me six tries to get the new fob accepted.

Also, if you didn’t hang on to that little red slip of paper you are absolutely done for.  Do not lose it.  Some of the horror stories I came across were from people who had bought their bike second-hand and not received the little red slip of paper.  Thankfully, any registered prefix code will work so technically I now have three options in an emergency.

So in addition to all of the things I am learning about what happens when you lose a parent, I also know how to program a key fob for a 2026 Yamaha XMAX 300.

And I am glad to have had the opportunity to learn these things, because I feel that people should take any opportunity to learn new things, but I can’t help feeling like the cost of some of these lessons is getting just a teensy bit unreasonable.

Oh, here’s that screenshot from the Yamaha manual I promised.  If you’ve been brought to this page because you are in the same situation I was in, I hope it’s helpful.
